Why Dura Cap?For years, trailer operators have been supplied with an inferior, cheaply manufactured, plastic axle cap. A $2,000 axle depending on a thin piece of plastic is a recipe for disaster. A lot of our customers, especially heavy haulers, would frequently melt or break their plastic caps. Dura Cap solves all these commonly found problems, while still providing you with the sight-glass window you need to easily see your axles oil level. Rugged aluminum construction means no overheating / melting or shattering. Heavy threads allow this cap to be torqued much more securely than a conventional plastic cap.Order your set of (4) or more Dura Caps today and take advantage of quantity discounts paired with FREE shipping!
